Jukebox

[Renich]

Hello, my PHP Freaks amigos!

 

I've made a jukebox (rockola) function to add a non-flash jukebox to my Creative Commons band... Anyway, the function works fine, so far, to me and I want to share it and see if anybody can improve it, since I'm not a good programmer.

 

Should I post it too sourceforge or something? Nah, probably isn't worth it... anyway!

 

Here it goes.

 

<?php

function rockola( $path, $rpath = null, $song = null, $desc = null )

	// define type
	if ( substr( $song, -3 ) == 'ogg' ) {
		$type = 'application/ogg';
	} else {
		$type = 'audio/mpeg';
	}

	// define object
	$object = <<< EOF

<object id="rockola_player" data="$song" type="$type" width="400" height="120">
<param name="autostart" value="true">
     	Lo siento, no puedes reproducir los formatos mp3 u ogg. Consíguete el quicktime o algo.
</object>

	// return data
	return $object;
}
